Abstract
The utility model relates to a rear suspension structure of a mining dump truck. The rear suspension structure is characterized in that: an A-shaped frame and a rear bridge are fixedly connected together; the front end of the A-shaped frame is connected to a torsion cylinder; one end of a rear suspension cylinder is connected to the rear bridge; and the other end of the rear suspension cylinder is connected to a rear tail base of a carriage. Seen from the side surface of the whole truck, the integrating body of the A-shaped frame and the rear bridge, the rear suspension cylinder and the carriage form a triangular stable structure, and connecting points are hinged by using joint bearings; and a transverse pull rod is used for limiting the whole transverse throw of the rear suspension cylinder, so the action force applied to the carriage by a road surface through a driving wheel in each direction and torque of the action force can be stably and reliably transferred. The utility model aims to provide a suspension system which is good in comfort and high in reliability and can transfer a higher driving and braking force.
Description
Technical field
The utility model relates to a kind of quarry tipper rear suspension structure, belongs to the quarry tipper field.
Background technology
The environment for use of quarry tipper is abominable; Need often go at rugged road surface and heavily loaded uphill/downhill, be delivered to vertical reaction on the vehicle frame, vertically counter-force, lateral reaction and all bigger through drive axle by moment that these counter-forces caused by the road surface.Traditional suspension system of being made up of elements such as steel spring, bumper, longitudinal rods is all can not satisfy above-mentioned environment for use from the traveling comfort angle of taking or from the reliability aspect.
Summary of the invention
The purpose of the utility model be to provide a kind of traveling comfort good, can transmit big driving and braking force, quarry tipper rear suspension structure that reliability is high.
Technical solution:
The utility model A type frame and back axle are fixed together, and the front end of A type frame is connected on the torsion tube of vehicle frame; Rear overhang cylinder one end is connected on the back axle, and the other end is connected on the back tailstock of vehicle frame; Intermediate rod one end is connected with back axle through oscillating bearing, and the other end is connected on the back tailstock of vehicle frame.
The utility model sees from the side of car load, formed a leg-of-mutton rock-steady structure by complex, rear overhang cylinder, the vehicle frame of A type frame and back axle, and adopted oscillating bearing hinged between each point of connection; Intermediate rod is used for limiting the horizontal throw of rear suspension single-piece, and transmission that like this can be reliable and stable is acted on the application force and the moment thereof of all directions on the vehicle frame through drive wheel by the road surface.
A type frame is by high-intensity casting alloy manufacturing, and its structure and profile are designed to the shape of a similar letter " A " according to its strained condition, and it is to link together with back axle through 2 at the rear portion, anteriorly connects together through any and vehicle frame.Because it is to manufacture abnormity according to its strained condition; Adopt two trailing arm structures of two longitudinal rods with respect to traditional suspension; It can bear bigger vertical counter-force (braking force and propulsive effort) on the one hand; It is the structure that is similar to a single longitudenal arm on the other hand, makes structure simplify more, has improved its reliability and maintainability.
The rear overhang cylinder of variable nitrogen/oil ratio unites two into one the function of elastic element and bumper; Make the structure of rear suspension more simplify; And different according to road surface situation and load carrying ability; Change the damping and the rigidity of hanging cylinder through the ratio that changes the nitrogen G&O, can obtain different outstanding cylinder performances, adapt to various environments for use.
One end of intermediate rod is connected on the back tailstock of vehicle frame, and the other end is connected on the back axle, and point of connection adopts oscillating bearing.Its effect mainly is the horizontal throw of restriction rear suspension, and the horizontal throw that can control rear suspension through the length of controlling it is in a reasonable range.
Description of drawings
Fig. 1 is the utility model structural representation;
Fig. 2 is the birds-eye view of Fig. 1.
The specific embodiment
The utility model A type frame 1 is hinged on through oscillating bearing on the torsion tube of vehicle frame, and back axle 3 is fixed together through bolt 2 with A shape frame 1; Rear overhang cylinder 5 is connected on the back axle 3 through oscillating bearing one end, and the other end is connected on the back tailstock of vehicle frame; Intermediate rod 4 is connected on the back axle 3 through oscillating bearing one end, and the other end is connected on the back tailstock of vehicle frame.Transmit by A type frame 1, rear overhang cylinder 5, intermediate rod 4 through application force and moment thereof that drive axle is delivered to all directions on the vehicle frame by the road surface, can control the horizontal maximum throw of rear suspension through the length of control intermediate rod 4.
