This three-wheel vehicle stability is when driving relatively poor, when the road surface simultaneously contacted has certain diff-H, the rollover of three-wheel vehicle easily occurs with two front-wheels.
Summary of the invention
The utility model technical issues that need to address: provide a kind of electricity to rub car front-wheel mechanism, the application of this front-wheel mechanism makes the travel safety of three-wheel vehicle good.
For solveing the technical problem, the technical solution of the utility model: a kind of electricity rubs car front-wheel mechanism, comprise front-wheel, leading axle and tap handle, it is characterized in that, two front-wheels are set together side by side, and two front-wheels are equipped with shock absorber, and the bottom of shock absorber is fixed on wheel shaft, the upper end of shock absorber is fixed with connector, and the both ends being articulated in the fork on leading axle by pivot are actively coupled with connector respectively.Described connector can be plate, and also can be coupling block, connector be arranged on the upper end of shock absorber, and in order to provide a stable erecting stage, the fork being convenient to connect shock absorber and leading axle is connected.Tap handle is fixed on the upper end of leading axle, when pulling tap handle, by leading axle, fork, shock absorber and make front-wheel be partial to.
As preferably, be fixed with connecting column on the coupling, the end of fork is connected on connecting column actively.Be provided with connecting column, many forks can be set between connecting column and leading axle, and make the connectivity robustness between leading axle and front-wheel good, be convenient to transmission when turning to.
As preferably, described fork comprises upper pendulum bar and draft link, and upper pendulum bar is positioned at the below of draft link.Upwards be provided with fork at the upper and lower of leading axle, further increase the stability of leading axle, and be convenient to the transmission of leading axle.
As preferably, upper pendulum bar is one, and upper pendulum bar is positioned at the front side of leading axle; Draft link is two, and two draft links divide the front and rear sides being listed in leading axle.Three forks are triangularly arranged, and effectively can improve the stability of Joint strenght and connection, are convenient to leading axle and control turning to of front-wheel.
As preferably, the middle part of pitman is connected in the lower end side of leading axle actively, and the two ends of pitman are actively coupled with two connectors respectively.Also be provided with pitman in the lower end side of leading axle, further increase the connective stability between leading axle and shock absorber.
As preferably, be fixed with bridge plate in the bottom of leading axle, the outer end of bridge plate and the medium position of pitman are actively coupled.Realizing the driving coupling of leading axle and pitman by arranging bridge plate, being convenient to arrange pitman, avoid pitman to produce movement interference.
As preferably, in the middle part of pitman and end positions place be provided with the coupling head of Qian shape respectively actively, the prong of these three coupling heads is articulated with set coupling spindle on two connectors and bridge plate outer end respectively.These three coupling heads both facilitated joint transmission, also effectively can adapt to the swing between them simultaneously.
As preferably, be provided with pad wheel in the prong of coupling head, pad wheel is socketed on coupling spindle with gap.Be provided with pad and take turns the swing requirement that can adapt to well between each corresponding component, flexible swinging is good.
Therefore, the beneficial effects of the utility model: owing to being fixed with shock absorber on the wheel shaft of front-wheel, this has adapted to the requirement that gait of march is high, load carrying ability is large of inhuman power-actuated three-wheel vehicle well.Because shock absorber itself has certain axial scalability, when the ground that two front-wheels contact has certain diff-H simultaneously, the telescopic nature of shock absorber can make up this diff-H well, and make the entirety of three-wheel vehicle can not present inclination by a relatively large margin, even if when occurring rolling, also can make to roll pace of change slow under the effect of shock absorber, this ensure that the travel safety of three-wheel well.Realize and the connecting of shock absorber by being articulated in fork on leading axle, the swing of fork effectively can adapt to surface conditions, is provided with tap handle and leading axle, facilitates and turns to three-wheel vehicle.
