Problems solved by technology

[0002] At present, heavy-duty vehicles are developing towards large tonnage, high power, and multi-axle. With the implementation of GB1589-2004, different forms of double front axle models have been developed in China. At present, the existing double front axle suspension devices in China use double front axles. The structural form of eight-point support, four leaf springs are respectively connected by eight support seats, although the existing double front axle suspension device adopts the structure of double front axle eight-point support can also play a certain suspension effect, but there are the following deficiencies, Disadvantages such as large wheelbase of double front axles, uneven distribution of axle loads, weight of the whole vehicle, and poor movement coordination of double front axles

Abstract

The invention relates to a vehicle suspension technique, especially the dual-front-bridge six-point support suspension device, wherein six support bases are connected to four sheet springs; via matching 14.00-20 tyre, it can effectively shorten the dual-steering front bridge axle distance, to confirm the axial load balance of dual front bridges, with compact structure and low weight; the rigidities of first and second front sheet springs are 242N / mm; the deflection frequency of suspension support is 81(n / min), to make the vehicle with buffered impact, damped vibration and adjusted vehicle position.

Description

Technical field: [0001] The invention belongs to the field of vehicle suspension, and in particular relates to a vehicle double front axle suspension device. Background technique: [0002] At present, heavy-duty vehicles are developing towards large tonnage, high power, and multi-axle. With the implementation of GB1589-2004, different forms of double front axle models have been developed in China. At present, the existing double front axle suspension devices in China use double front axles. The structural form of eight-point support, four leaf springs are respectively connected by eight support seats, although the existing double front axle suspension device adopts the structure of double front axle eight-point support can also play a certain suspension effect, but there are the following deficiencies, The double front axles have large wheelbase, uneven distribution of axle loads, the weight of the whole vehicle, and poor coordination of movement of the double front axles. ...
