Abstract
The utility model discloses the few plate spring of a kind of CDV car variation rigidity, comprise arc mainboard spring; Mainboard spring bottom is provided with subplate spring, and subplate spring bottom is provided with support, and mainboard spring, subplate spring are connected with the center bolt of support by middle part; Mainboard spring two ends are respectively arranged with left and right grasswort, are respectively arranged with left and right rubber bush in left and right grasswort; Subplate spring is connected with left and right rubber cushion blocks respectively by bolt above two ends; The thickness of mainboard spring and subplate spring is all for by the centre variable section structure thinning gradually to two ends.The utility model advantage is when load is less, only mainboard spring work, subplate spring provides support to mainboard spring when the load is increasing, major and minor leaf spring works simultaneously, achieve the variation rigidity of few plate spring, simultaneously left and right rubber cushion blocks, make friction and noise between major and minor leaf spring less, traveling comfort is better; Effectively reduce the noise and the vibration that are transmitted to car body by suspension, improve the NVH performance of vehicle, successful is improved to traveling comfort.
Description
Technical field
The utility model relates to suspension field, CDV vehicle chassis, especially relates to the few plate spring of a kind of CDV car variation rigidity.
Background technology
CDV vehicle, namely from the van transporter that car platform derives, adopts passenger-car chassis, self-supporting body.Be required to meet manned and dual requirements that is loading, the special suspension system of Structure of need could meet operating needs.The suspension load-carrying capacity of general car is limited, cannot meet the requirement of loading; And common Leaf Spring Suspension is used for the manned requirement that can not meet traveling comfort; Meanwhile, CDV vehicle have employed self-supporting body, and suspension noise is more easily delivered to interior.
Summary of the invention
It is little that the utility model object is to provide a kind of deadweight, and variable rigidity, travelling comfort is good, and load-carrying capacity is high.
For achieving the above object, the utility model can take following technical proposals:
The few plate spring of CDV car variation rigidity described in the utility model, comprises arc mainboard spring; Described mainboard spring bottom is provided with subplate spring, and described subplate spring bottom is provided with support, and described mainboard spring, subplate spring are connected with the center bolt of support by middle part; Described mainboard spring two ends are respectively arranged with left and right grasswort, in described left and right grasswort, be respectively arranged with left and right rubber bush; Left and right rubber cushion blocks is connected with respectively by bolt above described subplate spring two ends; The thickness of described mainboard spring and subplate spring is all for by the centre variable section structure thinning gradually to two ends.
The utility model advantage is when load is less, only mainboard spring work, subplate spring is provided support to mainboard spring by the left and right rubber cushion blocks installing its two ends when the load is increasing, major and minor leaf spring works simultaneously, achieve the variation rigidity of few plate spring, simultaneously by adding left and right rubber cushion blocks, to make between major and minor leaf spring friction and noise less, provide traveling comfort more better than common few plate spring; By being pressed into left and right rubber bush in the left and right grasswort of mainboard spring, effectively reducing the noise and the vibration that are transmitted to car body by suspension, improve the NVH performance of vehicle, successful is improved to traveling comfort.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
As shown in Figure 1, the few plate spring of CDV car variation rigidity described in the utility model, comprises arc mainboard spring 1; Described mainboard spring 1 bottom is provided with subplate spring 2, described subplate spring 2 bottom is provided with support 3, described mainboard spring 1, subplate spring 2 are connected with the center bolt 4 of support 3 by middle part; Described mainboard spring 1 two ends are respectively arranged with left and right grasswort 5,6, in described left and right grasswort 5,6, be respectively arranged with left and right rubber bush 7,8; Left and right rubber cushion blocks 9,10 is connected with respectively by bolt above described subplate spring 2 two ends; The thickness of described mainboard spring 1 and subplate spring 2 is all for by the centre variable section structure thinning gradually to two ends.
