Abstract
The utility model relates to a novel two-wheel frame structure. A saddle frame (support column) is connected with a rear axle frame to be in an S shape. A point which is arranged in the middle of the S-shaped frame is connected with the rear portion of a main frame to be in an X shape in a bearing mode. The distance between the saddle frame (3) and a main frame pedal portion (9) is no shorter than that between a main frame tail portion (5) and a rear wheel. Under the effect of gravity without a rider, the height of the saddle frame (3) is higher than that when normally moving on the road, a lever principle plays a role when moving on the concave road, and a rear wheel middle shaft (7) moves downward along the concave road.
Description
Technical field:
The utility model relates to shape and the structure of a kind of cart (bicycle, Electrical Bicycle, battery-operated motor cycle, motor bike) vehicle frame.
Background technology:
At present, known cart mounting (pillar stiffener) all is integrated with car owner's frame.The driver travels when concavo-convex road surface, though the rear wheel shock-absorbing device is played a role, anti seismic efficiency is single.
Summary of the invention:
The utility model provides a kind of cart frame because the frame person of taking advantage of weight concentrates on postmedian, so this cart in the process of moving not only trailing wheel can move ahead with concavo-convex road surface, and Carrier for cycle (pillar stiffener) also can move with concavo-convex road surface reversing sense.Make the frame person of taking advantage of upper body at utmost with whole road surface keeping parallelism, thereby reach desirable anti seismic efficiency.
Technical scheme:
The technical scheme that its technical matters that solves the utility model adopts is: Carrier for cycle (pillar stiffener) and trailing wheel pedestal are connected to S shape, establishing at S shape frame middle part is that bearing connects into X-type with the main car frame rear portion a bit, take this point of connection as the center of circle, take less than this point to hind axle as radius, establish at 2 main car frame and S shape and be the bumper point of connection.Vehicle seat is connected for spring with Carrier for cycle (pillar stiffener).
Advantage and effect:
The beneficial effects of the utility model are under the lever principle and rear shock absorber effect of S shape frame and main car frame point of connection, Carrier for cycle (pillar stiffener) can be done up and down reversing sense motion with trailing wheel axis (being concavo-convex road surface), below-seat is spring shock-absorbing, and the assurance driver's is comfortable.
Description of drawings:
Below in conjunction with accompanying drawing the utility model is further specified, Fig. 1 is this cart shelf structure scheme drawing: vehicle seat (1), spring (2), Carrier for cycle (3) X-shaped adapter shaft (4), main car frame afterbody (5), rear shock absorber (6), trailing wheel axis (7), S shape link span (8), main car frame pedal position (9), crown prince's formula front truck are (10).
The specific embodiment:
1, as shown in Figure 1: Carrier for cycle (3) to main car frame pedal position (9) distance be not less than main car frame afterbody (5) to track rear from.Under without driver's Action of Gravity Field, Carrier for cycle (3) should be higher than height when normally travelling on the road surface, can bring into play lever principle when travelling on recessed road surface with assurance, and trailing wheel axis (7) is moved downward with recessed road surface.
2, in the drawings (10) are crown prince's formula handlebar (except the bicycle), and the driver can be unaffected during with assurance Carrier for cycle up-and-down movement, thereby control handle assurance traffic safety well.
If 3, the utility model is furnished with large volume storage battery or driving engine, should be placed in as shown in Figure 1: main car frame pedal position (9) or front lower place (except the bicycle), drive steadily with assurance.
Claims (2)
1. a cart shelf structure relates to and comprises bicycle, Electrical Bicycle, battery-operated motor cycle, motorcycle frame structure, it is characterized in that the shaft connection place is integrated into S shape in Carrier for cycle and the trailing wheel.
2. a kind of cart shelf structure according to claim 1 is characterized in that it is that bearing connects into X-shaped with cart frame rear portion a bit that S shape middle part has.
