Description
Technical field
The utility model relates to the rear-suspension system of various carrying, goods carrying vehicle, is specially adapted to the rear-suspension system that chassis is higher.
Background technology
Its left and right wheels of dependent suspension can be implicative of each other when bouncing, and the advantages such as tyre angle variable quantity is little, tire wear is little, road-holding property is good, structure is simple, low cost of manufacture are widely used in the rear-mounted field of goods carrying vehicle.Modal at lorry rear axle suspension is Leaf Spring Suspension, although Leaf Spring Suspension load-carrying capacity is strong, it is too heavy, and in vehicle travel process, every sheet steel plate all can up-and-down movement, thus produces friction, is difficult to the path of motion adjusting steel spring.In addition, BF can not be coordinated mutually with the cross motion of axletree, and limits vehicle body without sway bar and rock, and that is steel spring can act directly on transverse force in overall vehicle bridge, so it is poor for the buffering effect of horizontal force.
Utility model content
The utility model is according to above not enough, provide a kind of isometric pair of longitudinal tie formula spiral spring rigid axle suspension, after this suspension is connected with vehicle body, parallel-crank mechanism is constituted owing to waiting vehicle body end support, isometric pair of longitudinal tie (isometric pair of trailing arm) and the support be fixed in vehicle bridge, the path of motion of car load can be controlled accurately, according to the principle of parallel-crank mechanism, when axle tramp, vehicle bridge and vehicle body remain constant relative to the angle of Z axis.
The technical solution of the utility model is:
A kind of isometric double trailing arm type spiral spring rigid axle suspension, is characterized in that, comprising:
Vehicle body;
Bumper bridge end support, is provided with two, is respectively used to installation car rear axle, one end of bumper bridge end support through bumper and vehicle body hinged;
Longitudinal tie bridge end support, fixes with bumper bridge end support;
Upper longitudinal tie, lower longitudinal tie, both be arranged in parallel and length is identical, and one end and the vehicle body of upper longitudinal tie and lower longitudinal tie are hinged, and the other end of upper longitudinal tie and lower longitudinal tie is hinged with the other end of longitudinal tie bridge end support, bumper bridge end support respectively;
Coil spring bridge end bearing, fixes with car rear axle;
Spacing rubber block, fixes with coil spring bridge end bearing;
Coil spring, bottom to be fixed on coil spring bridge end bearing and to be enclosed within outside spacing rubber block, and vehicle body end bearing is fixed at top, and vehicle body end bearing and vehicle body are fixed, and vehicle body end bearing is fixed with limiting stopper, and limiting stopper inserts helical spring top;
Anti-dumping intermediate rod, one end and car rear axle hinged, the other end and vehicle body hinged, anti-dumping intermediate rod and car rear axle are in same plane.
As preferably, the angle of described bumper and vertical direction is 15-30 degree.
As preferably, the angle of described anti-dumping intermediate rod and car rear axle is 15-30 degree.
As preferably, described bumper is cylinder type hydraulic beidirectional bumper.
The beneficial effects of the utility model: isometric double trailing arm type spiral spring rigid axle suspension can control the path of motion of vehicle rear axle accurately; And the coil spring of spiral spring rigid axle suspension comparatively steel spring, coil spring can provide larger axle articulation, the wheel of load is made to have larger stroke up and down, in addition can not there is internal friction loss in coil spring, thus make bumper have better control to spring, improve vehicle travel time handling.The weight of coil spring mechanism is also very light, and can design with different diameters and length, therefore also can be applicable to the demand of various different automobile types.Helical spring type dependent suspension designs sway bar usually, can play the buffering effect of good horizontal force.In addition, helical spring lightweight, can complete vehicle weight be reduced.
