The invention discloses an anti-nodding device for a front wheel brake of an electric vehicle which comprises a front wheel and two fixing rods which are bilaterally symmetrical about the front wheel, each fixing rod is internally provided with a damping component for reducing vibration, and the lower side of each damping component is provided with an auxiliary damping component for avoiding brake nodding. The device is provided with an auxiliary damping component, when a front wheel is braked, an upper conductor and a lower conductor make contact, an electromagnet is powered on, then an annular lifter has upward supporting force, the situation that a vehicle nodding happens is prevented, meanwhile, a buffer spring plays a role in normal damping before a sealing gasket is about to descend to the lower limit position, the pressure in the hydraulic cavity is prevented from being too large, and the safety of vehicle driving is guaranteed.
本发明公开了一种电动车前轮刹车防点头装置,包括前车轮以及两个关于所述前车轮左右对称的固定杆,每个所述固定杆内均设有降低震动的减震构件,所述减震构件的下侧设有避免刹车点头的辅助减震构件,本发明装置设有辅助减震构件,在前轮发生刹车时,上下两个导体接触,电磁铁通电,进而环形升降器具有向上的支撑力,防止车辆发生点头的情况,同时缓冲弹簧在正常的减震中在密封垫将要下降到下极限位置之前起到作用,避免液压腔内的压力过大,保证车辆行驶的安全性。
