Abstract
The utility model discloses a longitudinal shockproof suspension mechanism for an electric vehicle, comprising a vehicle frame, four tires, a rear axle, a front axle, a left steering bracket, a right steering bracket and a steering column, two tires are respectively mounted at the left and right sides of the front axle, the other two tires are mounted at the left and right sides of the rear axle, the left steering bracket and the right steering bracket are mounted on the front axle, the vehicle frame is mounted on the rear axle and the front axle in a connecting manner, the steering column is fixedly connected with the vehicle frame, the longitudinal shockproof suspension mechanism is also provided with a leaf spring, one end of the leaf spring is fixedly connected with the front axle, the other end of the leaf spring is fixedly connected with the rear axle through a leaf spring press plate, and the vehicle frame is fixedly connected with the leaf spring. The longitudinal shockproof suspension mechanism for the electric vehicle is simple in structure, low in cost and has good damping effect.
Description
Technical field
The utility model relates to a kind of shock-absorbing suspension mechanism of battery-driven car, especially a kind of vertical shock-absorbing suspension mechanism of mini electric vehicle.
Background technology
At present miniature electric automobile development rapidly, and the shock-absorbing suspension mechanism that is applicable to miniature four-wheel vehicle adopts coil spring and coil spring supporting construction mostly, this structure complex structure for mini electric vehicle is many, cost is higher, and damping effect is bad.
Summary of the invention
The purpose of this utility model be to provide a kind of simple in structure, cost is low and the vertical shock-absorbing suspension mechanism of the battery-driven car of good damping effect.
in order to achieve the above object, the technical solution of the utility model is: the vertical shock-absorbing suspension mechanism of a kind of battery-driven car, comprise vehicle frame, four tires, back axle, propons, the left steering support, right steering support and steering column, two tires are contained in respectively the left side of propons, right both sides, another two tires are contained in the left side of back axle, right both sides, left steering support and right steering support all are contained on propons, vehicle frame is installed on back axle and propons, steering column is captiveed joint with vehicle frame, its innovation is: also have leaf spring, one end of leaf spring is captiveed joint with propons, the other end is captiveed joint with back axle by panel spring hold-down plate, vehicle frame is captiveed joint with leaf spring.
Described leaf spring is two, and the leaf spring connecting frame is housed on vehicle frame, and the leaf spring connecting frame is captiveed joint with two leaf springs.
After adopting said structure, owing to also having leaf spring, an end and the propons of leaf spring are hinged, the other end is captiveed joint with back axle by panel spring hold-down plate, vehicle frame is captiveed joint with leaf spring, therefore makes spring structure into vertical plate spring structure, and leaf spring is connected with vehicle frame, greatly simplify the structure, improved damping effect, and for the SF structure, vertically the plate spring structure part is few, lightweight and easy for installation, cost is low, good damping effect is highly suitable for mini electric vehicle.
Description of drawings
Fig. 1 is blast block diagram of the present utility model.
The specific embodiment
The embodiment that provides below in conjunction with accompanying drawing is described in further detail the utility model.
shown in Figure 1, the vertical shock-absorbing suspension mechanism of a kind of battery-driven car, comprise vehicle frame 1, four tires 2, back axle 3, propons 4, left steering support 5, right steering support 6 and steering column 7, two tires 2 are contained in respectively the left side of propons 4, right both sides, another two tires 2 are contained in the left side of back axle 3, right both sides, left steering support 5 and right steering support 6 all are contained on propons 4, vehicle frame 1 is installed on back axle 3 and propons 4, steering column 7 is captiveed joint with vehicle frame 1, also has leaf spring 8, one end of leaf spring 8 is captiveed joint with propons 4, the other end is captiveed joint with back axle 3 by panel spring hold-down plate 9, vehicle frame 1 is captiveed joint with leaf spring 9.
Shown in Figure 1, in order better vehicle frame 1 to be connected on leaf spring 8, and be connected firmly, described leaf spring 8 is two, leaf spring connecting frame 10 is housed on vehicle frame 1, leaf spring connecting frame 10 is captiveed joint with two leaf springs 8, adopt like this two leaf springs 8 just can better play damping effect, and structure is very reliable.
Shown in Fig. 1,2,3, the utility model has improved damping effect more for the SF structure, and part is few, lightweight, easy for installation, good damping effect, more is applicable to the shockproof suspension of mini electric vehicle.
