The vehicle driven by muscle power of the driver
(57) Abstract:The invention relates to a frame of a tricycle, providing the suspension axis of the rear wheels. Between the two parts of the frame and inside of these parts are placed intermediate 3. This link has 3 horizontal 5 and 6 vertical axis, which provide a hinged connection of the parts of the frame. Shock vertical axis 6 provides the taxiing rear wheel, and a shock absorber horizontal axis 5 depreciation rear wheels. You have the option of blocking horizontal swivel of the two parts of the frame relative to the vertical axis 6 by means of the lock 8, 9. The proposed solution is aimed at improving the maneuverability. 1 C.p. f-crystals, 3 ill. The invention relates to transport machinery, and more particularly to a vehicle driven by muscle power of the driver, and is used mainly in the field of tourism, as well as for transportation of small loads over short distances. This area is ecologically clean technology is rapidly developing and constantly improving.The inventive vehicle driven by muscle force volitive which has a housing, two mutually perpendicular axes shock absorbers, one for each swivel and locking device for locking the horizontal swivel, wheel, wheel, driver seat, bike the drive, including a carriage with two cranks and pedals, leading and driven sprocket, drive shaft, kinematically linked with the drive wheels.Currently known bike (ed. St. 1104045, CL 62 To 5/02), containing frame is made of two parts, pivotally interconnected by means of horizontal axles, wheels, driver seat, pedal-and-rod drive, front wheel steering with steering shaft and rods connected with the rear wheels.Also known bike (U.S. Pat. USA 4456277, CL 62 To 23/06) with the wheel formula 2-1, driven by a cyclist that contains a frame, a front unit having two driven front wheels, mechanism for driving the front wheels, the seat, one trailer rear wheel mounted on the frame, a device for turning the front wheels, bike wheel drive the front wheels, which affects the cyclist. Seat mounted on the frame behind the front wheels, provides located the AME under the seat.The closest technical solution is a vehicle (U.S. Pat. RF 2106278 C1, CL 62 To 5/02), driven by muscle power of the driver containing the base, consisting of two parts adjustably connected by a horizontal axle, wheels, wheel drive front wheel drive, driver seat, bike the drive, including a carriage with two cranks and pedals, the driving and the driven sprocket with chain transmission, a drive shaft kinematically connected with front-wheel drive.In view of the rigidity of the frame in a horizontal plane specified vehicle has low performance when driving on uneven roads (gravel roads, uneven patches with bumps and other) and while maneuvering in a complex environment (Parking, traffic between the trunks of trees, etc), as well as a lack of protection from the horizontal dynamic loads of the attachment points of the rear wheels and the rear wheels.The objective of the invention is the improvement of the operational characteristics of the vehicle and reducing the impact of horizontal dynamic loads on the vehicle. This is achieved in that between the two offered connection with parts of the frame, having in its composition body with hosted two mutually perpendicular axes and two shock absorbers, one for each pivot connection, and one of the parts of the frame, next to the intermediate hosted a locking device for locking the horizontal hinge connection between the two parts of the frame, consisting of a rolling element made interoperable with the case of intermediate and drive rolling element.In Fig. 1 is a perspective view of the vehicle of Fig.2 is a top view in Fig.1; Fig.3 - section a-a in Fig.2.The vehicle driven by muscle power of the driver (see Fig.1-3), contains a frame made of two parts - the front 1 and rear 2, pivotally interconnected intermediate 3, in the housing 4 which is placed a horizontal and vertical axis 5 axis 6, and two shock absorber 7. On the front part of the frame 1 is installed movable element 8 of the locking device with the actuator 9, bike the drive, including the carriage 10 with cranks and pedals, sprocket 11 and the driven sprocket 12, the driving shaft 13, kinematically linked with the drive wheels 14, with his and the absorber 7. On the rear part of the frame 2 is installed follower wheel 17, the horizontal axis 5 and the absorber 7.The vehicle operates as follows. In rectilinear motion under influence of the driver on the crank pedal mechanism 9 torque is transmitted from the drive sprocket 11 on the driven sprocket 12, the driving shaft 13 and further to the drive wheels 14. Upon termination of the impact of the driver on the crank-pedal mechanism 10 freewheel wheels 14 are opened and the vehicle continues to move under the force of inertia. When turning the steering wheel 15 during the movement of the drive wheels 14 are rotated to the appropriate angle, changing the direction of movement of the vehicle.When driving on roads with smooth surface (asphalt, concrete, etc.,) the movable element 8 of the locking device 9 is in engagement with the casing 4 intermediate 3, except horizontal swivel movement of the rear frame 2 to prevent possible chattering of the latter at high speeds.When driving on uneven roads (gravel and dirt roads, meadows with bumps and others) and especially when maneuvering in a complex environment (Parking,ü horizontal swivel movement of the rear frame 2, providing an automatic maneuvering of the rear wheel 17 when the raids last on average obstacles (hills, large pebbles, medium boulders, covered with grass or sand, etc.,), then the shock absorber returns the wheel 17 in the position corresponding rectilinear movement of the vehicle, thereby increasing a comfortable environment for the driver and reduces the turning radius of the vehicle while maneuvering, which together significantly improves the operating characteristics of the vehicle, reduces the horizontal dynamic loads on the wheel 17 and leads to the expansion of the range of use of the vehicle. 1. The vehicle driven by muscle power of the driver containing a frame made of two parts adjustably connected, the driver's seat, steering wheel, wheels, bike the drive, including a carriage with two cranks and pedals, the driving and the driven sprocket, a drive shaft kinematically connected with the driving wheels, wherein the inside of the two parts of the frame are placed intermediate executed with a possibility of vertical and horizontal swivel with parts of the frames is forami - one for each pivot joint, shock absorber horizontal swivel is arranged to provide automatic maneuvering of the rear wheels of the vehicle.2. Vehicle under item 1, characterized in that one of the parts of the frame, near the housing intermediate hosted a locking device configured to lock the horizontal hinge connecting the two parts of the frame, consisting of a rolling element made interoperable with the case of intermediate and drive the locking device.
SUBSTANCE: invention relates to collapsible one-track ice mobiles. Ice mobile elements are integrated into three independent modules, that is, front support module 1, frame module 2 and rear support module 3. Hooks 17, 26 and retainers 1-3 hinge said modules together.
EFFECT: fast assembly-disassembly, smooth running.

SUBSTANCE: pendulum fork 8 of rear wheel 7 is coupled with frame 1 by hinge 18 and spring shock-absorber 9. Vertical force of arms is directly transmitted to pendulum fork 8 bypassing shock-absorbed 9 due to linkage of vertical rod 10 with fork 8 and its arrangement under seat. Note here that handle bar 6 is arranged on vertical rod 10 and coupled with front fork 5 by tie rods 11. In compliance with another version, shock-absorber 9 may be arranged ahead of tie rod 10.
EFFECT: reduced requirements to shock-absorber and perfected characteristics of suspension.
