The utility model is achieved by following technical solution:
A kind of four-wheel electric motor car foresteerage gear, comprise base and the front vehicle frame that is fixed in base front end top, both sides, described front vehicle frame top are separately installed with front forked bracket by adapter plate, in front forked bracket, be fitted with two the front fork rotating shafts in left and right, front fork rotating shaft bottom is connected with front fork, described front vehicle frame top middle portion is also connected with mount pad, on mount pad, be fitted with steering shaft, steering shaft top is provided with steering handwheel, steering shaft middle part is connected with spaced apart minor sprocket A and minor sprocket B, front fork rotating shaft top, two of described left and right is connected with respectively hinge wheel A and hinge wheel B, between hinge wheel A and minor sprocket A, hinge wheel B is all connected by chain with before minor sprocket B.
Described steering shaft bottom and top are socketed with respectively tapered roller bearing and deep groove ball bearing.
The diameter of described hinge wheel A, hinge wheel B is minor sprocket A, minor sprocket B diameter 4 times.
Described hinge wheel A is highly identical with minor sprocket A, and hinge wheel B is highly identical with minor sprocket B.
Described front vehicle frame top middle portion is connected with trapezoidal steering handwheel support, and steering shaft is through this steering handwheel support.
Described steering shaft and front fork rotating shaft all parallel with front vehicle frame front end face.
Described front vehicle frame front end face recedes, and inclination angle is 70 °.
The beneficial effects of the utility model are:
Compared with prior art, the four-wheel electric motor car foresteerage gear that the utility model provides, it drives steering shaft to rotate together with 2 minor sprockets by rotating steering handwheel, via minor sprocket, by 2 hinge wheels of chain-driving, rotate, and then drive front fork to rotate together with front-wheel, thereby realize, the moment of torsion on steering handwheel is passed to front-wheel rotation, have to turn to flexibly and stablize, operation is dexterous, simple in structure, practical advantage, efficiently solve the problem that traditional three-wheeled electric vehicle front-wheel only has a curved easy generation of existing mistake to roll or turn on one's side, there is good driving impression and safety performance.
Accompanying drawing explanation
Fig. 1 is front view of the present utility model;
Fig. 2 is the left view of Fig. 1;
Fig. 3 is the enlarged drawing of dotted portion I in Fig. 2;
In figure: 1-base, 2-front vehicle frame, 3-adapter plate, 4-front forked bracket, 5-front fork, 6-steering handwheel, 7-hinge wheel A, 8-hinge wheel B, the rotating shaft of 9-front fork, 10-steering handwheel support, 11-column, 12-tapered roller bearing, 13-deep groove ball bearing, 14-front-wheel, 15-steering shaft, 16-mount pad, 17-minor sprocket A, 18-minor sprocket B, 19-chain.
The specific embodiment
Below in conjunction with drawings and Examples, the technical solution of the utility model is described further, but described in desired protection domain is not limited to;
As 1, shown in 2 and 3 figure, the four-wheel electric motor car foresteerage gear that the utility model provides, comprise base 1 and the front vehicle frame 2 that is fixed in base 1 front end top, described front vehicle frame 2 both sides, top are separately installed with front forked bracket 4 by adapter plate 3, in front forked bracket 4, be fitted with two the front fork rotating shafts 9 in left and right, front fork rotating shaft 9 bottoms are connected with front fork 5, described front vehicle frame 2 top middle portion are also connected with mount pad 16, on mount pad 16, be fitted with steering shaft 15, steering shaft 15 tops are provided with steering handwheel 6, steering shaft 15 middle parts are connected with spaced apart minor sprocket A17 and minor sprocket B18, front fork rotating shaft 9 tops, two of described left and right are connected with respectively hinge wheel A7 and hinge wheel B8, between hinge wheel A7 and minor sprocket A17, hinge wheel B8 is all connected by chain 19 with before minor sprocket B18.
