The specific embodiment

Provide as accompanying drawing 1 and accompanying drawing 2, the utility model includes vehicle frame triangular in shape 3, is provided with handlebar 1 at the nock of its vehicle frame, is equipped with vehicle seat 4 in the upper end at vehicle frame rear portion.Be respectively fitted with in the front lower ends of vehicle frame 3 and lower end, rear portion and place load-bearing front vehicle wheel 14 on the rail level and load-bearing rear wheel 5 on the track 8, its track 8 adopts the rigidity rail body of I-shaped cross-sections to be laid on the hillside.Being connected with vehicle frame 3 is provided with front vehicle wheel crotch 10 and the rear wheel crotch 7 that is extended to track 8 both sides by forward and backward bearing wheed wheel shaft place, is equipped with on two wheel crotch and the contacted steady wheel 11 of rail web face.Before assembling on the wheel shaft of bearing wheed 14 with the coaxial active drive gear 15 that is equipped with of preceding bearing wheed, its active drive gear be assemblied in front vehicle wheel crotch 10 on and be the driven driven wheel 12 that 90 ° of angles are provided with the active drive gear and be meshed, its driven driven wheel is meshed with tooth bar 9 on being arranged on track 8 web of the rail faces.Provide as accompanying drawing, its steady wheel that is assemblied on the rear wheel crotch is symmetrical arranged on the two sides, upper and lower, be assemblied in steady wheel on the front vehicle wheel crotch and be provided with a pair ofly in the bottom bilateral symmetry, another one is arranged on the opposite side with driven driven wheel symmetric position.Be equipped with the crank pedal 13 that drives 15 rotations of active drive gear in fixing two axial ends of assembling the wheel shaft of active drive gear 15.

Driving and driven driven

wheel

15,12 of the present utility model can adopt the sprocket teeth structure, with the tooth bar 9 of its phase configuration can adopt as Fig. 3 by flute profile support body 20 be distributed on the rack structure that the cylinder 21 on its flute profile support body is formed.

This bicycle for mountain-climbing is in the appropriate to the occasion employing of the going up a hill mode of riding backwards, and promptly " back of the body moves back " formula is advanced, and this moment, bicyclist's health was complied with domaticly, and down-shift of working center makes car body stability and safety more when advancing, and landscape under the mountain of being convenient to climb high and gaze far." back of the body moves back " when formula is advanced, in order to prevent that the downward hill wash of car body from moving, be provided with active drive gear backward rotation restriction ratchet 16, the rear end of this ratchet is hinged and connected on the vehicle frame, the leading section of its ratchet can embed in the gear teeth of active drive gear, by the reversing of restriction active drive gear, it is mobile to prevent that car body from gliding.When formula is advanced,, be equipped with back mirror 18 " back of the body moves back " in the upper end of vehicle frame front portion for the ease of observing situation after one's death.
