Description
Technical field
The utility model relates to battery-driven car parts, relates to a kind of battery-driven car leaf spring in particular.
Technical background
Leaf spring is the arc-shaped structure that two ends tilt, leaf spring two ends tilt part and are connected with vehicle frame, primary member is plate spring sheet, leaf spring clip and bolt, and the length of plate spring sheet is stepped successively decreases, and the annexes such as bolt and leaf spring clip are assembled into plate spring assembly, the plate spring sheet length of the superiors is maximum, hanger is bent out, for being installed on below car body by leaf spring, when leaf spring is stressed at its two ends, utilize the elastic force of leaf spring self, reach the effect of compensator or trimmer pressure.
But the load-carrying of car is more sometimes, leaf spring meeting excessive deformation, affects service life and the elasticity of leaf spring.At present, the plate spring structure of battery-driven car adopts traditional leaf spring, when electronic underloading, due to rigidity and the camber limitation in height of leaf spring self, the deadweight of battery-driven car is not enough to make the camber of leaf spring that due change occurs, thus the effect of damping can not be played, under steam, make battery-driven car have sense of significantly jolting; When battery-driven car heavy service, the swing due to vehicle frame make leaf spring and vehicle frame connecting portion as easy as rolling off a log impaired, more serious, when super section of vehicle, because load-carrying exceeds the tolerance range of leaf spring, cause leaf spring to produce plastic deformation, permanent infringement is caused to leaf spring self.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of battery-driven car leaf spring.
For solving the problems of the technologies described above, the utility model provides a kind of battery-driven car leaf spring, comprise main spring, auxiliary spring and bolt, described auxiliary spring is divided into auxiliary spring and lower auxiliary spring, and lay respectively at two sides up and down of main spring, all cushion block is installed between described upper auxiliary spring and main spring and between lower auxiliary spring and main spring, described bolt is by upper auxiliary spring, main spring, cushion block, the intermediate link of lower auxiliary spring is as a whole, the two ends of described upper auxiliary spring and lower auxiliary spring are equipped with leaf spring clip, described leaf spring clip is by upper auxiliary spring, lower auxiliary spring and main spring are fixed, downside two end of described upper auxiliary spring and upside two end of lower auxiliary spring are all provided with snubber block.
Further, described main spring is rectangle, and bending two ends becomes hanger.
Further, the shape of described upper auxiliary spring and lower auxiliary spring is two ends tilting, umbilicate circular arc.
Further, described snubber block is bolted on auxiliary spring.
Further, described cushion block is small-sized leaf spring.
Further, described main spring, upper auxiliary spring and lower auxiliary spring are all superposed by several plate spring sheet and form.
The beneficial effect of employing technique scheme is: a kind of battery-driven car leaf spring of the present utility model, and structure is simple, in the middle of main spring and auxiliary spring, install cushion block, and utilize main spring, interaction between auxiliary spring and snubber block, thus more comfortable when making car underloading, more can carry during heavy duty, avoid because when vehicle overload carries, plastic degeneration appears in leaf spring, driving more has safety, greatly can improve the service life of car, technique is simple, easy to manufacture simultaneously, and cost is low, dependable performance, meets the demand of consuming.

Fig. 1 is the structural representation of a kind of battery-driven car leaf spring of the utility model,
Wherein, 1, main spring, 2, upper auxiliary spring, 3, lower auxiliary spring, 4, cushion block, 5, bolt, 6, snubber block, 7, hanger, 8, leaf spring clip.
Detailed description of the invention
Below in conjunction with Figure of description, the technical solution of the utility model and structure are described, so that those skilled in the art understand.
A kind of battery-driven car leaf spring, comprise main spring 1, auxiliary spring and bolt 5, described auxiliary spring is divided into auxiliary spring 2 and lower auxiliary spring 3, and lay respectively at two sides up and down of main spring 1, between described upper auxiliary spring 2 and main spring 1 and between lower auxiliary spring 3 and main spring 1, cushion block 4 is all installed, described bolt 5 is by upper auxiliary spring 2, main spring 1, cushion block 4, the intermediate link of lower auxiliary spring 3 is as a whole, the two ends of described upper auxiliary spring 2 and lower auxiliary spring 3 are equipped with leaf spring clip 8, described leaf spring clip 8 is by upper auxiliary spring 2, lower auxiliary spring 3 and main spring 1 are fixed, downside two end of described upper auxiliary spring 2 and upside two end of lower auxiliary spring 3 are all provided with snubber block 6.
Further, described main spring 1 is rectangle, and bending two ends becomes hanger 7.
Further, the shape of described upper auxiliary spring 2 and lower auxiliary spring 3 is two ends tilting, umbilicate circular arc.
Further, described snubber block 6 is bolted on auxiliary spring.
Further, described cushion block 4 is small-sized leaf spring.
Further, described main spring 1, upper auxiliary spring 2 and lower auxiliary spring 3 are all superposed by several plate spring sheet and form.
Above-mentionedly by reference to the accompanying drawings utility model to be exemplarily described; obvious the utility model specific implementation is not subject to the restrictions described above; as long as have employed this insubstantial that method of the present utility model is conceived and technical scheme is carried out to improve; or the design of utility model and technical scheme directly applied to other occasions, all within protection domain of the present utility model without to improve.
