Abstract

Disclosed is a front and rear suspension assembly on the truck engine. The assembly comprises a metal inner bushing and a bracket and is characterized in that: a round cover is fixed on upper end of the metal inner bushing. The inner bushing is in a T-shaped. A rubber covered below the round cover is fixed with a wearable jacket outside the rubber of the lower part of the inner bushing and a pad is plugged at lower end of the inner bushing. The utility model enlarges the bottom contacting area of the engine suspension assembly. The contacted face and side are made of the wearable material, therefore solving the previous wear problems of the engine pad and enhancing the wear and durability performance of the assembly. The utility model can achieve the purpose of the duration 30000 kilometer under the bad weather. Compared with the prior art, the utility model increases the service life more than 50 times.

Description

Mounting assembly before and after the truck engine

Affiliated technical field

The utility model relates to the suspending cushion of truck engine bottom.

Background technology

At present, be installed to light, the suspending soft cushion assembly structure is "T"-shaped cylinder by the outside coated one deck rubber of an inner metal sleeve pipe before and after the driving engine on two kinds of vehicles of heavy truck, cylinder is inserted in the carriage, its bottom and cylindrical sides all are rubber, cylindrical structure is softer, on it, contact with driving engine bottom and carriage respectively below, the bottom surface area of contact is little, in use go up, following cracky, side and bracket hole friction, loss is very fast, under condition of severe, can only use the 400-600 kilometer, suspending soft cushion assembly after the wearing and tearing produces influence greatly to the in-use performance of car load, must often change, and brings bigger trouble to the user.

Summary of the invention:

The purpose of this utility model is to provide that a kind of wear resisting property is good, mounting assembly before and after the truck engine of long service life, to solve the problem that prior art exists.The purpose of this utility model realizes by technical scheme shown in the drawings, it comprises an inner metal sleeve pipe, the outer coated one deck rubber of inner sleeve, form the cylinder of a band round platform, its lower end is inserted in the carriage, it is characterized in that the affixed dome in inner metal sleeve pipe upper end, inner sleeve is "T"-shaped, the outer coated rubber of dome below and inner sleeve, wear-resisting sheath of inner sleeve bottom rubber external fixation, pad of inner sleeve lower end grafting.For increasing area of contact, bracket hole protects skirt downwards.

After adopting said structure, strengthened engine mounting assembly bottom area of contact down, above and the side all be high-abrasive material, avoided above the mounting assembly, side rubber contacts with metallo-, the outer coated rubber of inner sleeve has played damping and buffering effect again simultaneously, solved driving engine cushion problem easy to wear in the past, improved wear-resisting, the durability of mounting assembly, the utility model is 30,000 kilometers in harsh environment following service life, common township road is 60,000 kilometers, express highway is 300,000 kilometers, improves service life more than 50 times than prior art.

Description of drawings

Accompanying drawing is the utility model structure cutaway view.Legend: 1, T shape inner sleeve; 2, rubber bodies; 3, wear-resisting sheath; 4, pad; 5, carriage; 6, carriage protects skirt.

The specific embodiment

Further specify the utility model below in conjunction with drawings and Examples.Inner sleeve adopts No. 45 steel pipes, and its upper end throat depth is a disk of 70 millimeters of 4 millimeters, diameter, becomes T shape, and inner sleeve vulcanizes one deck rubber outward.Side sheaths adopts nylon sheath wire, with the vulcanization of rubber together.Pad is a rubber bodies, circle, and 65 millimeters of diameters, are plugged on the lower end of inner sleeve by thick 17 millimeters.Carriage protects high 15 millimeters.

Claims

1, mounting assembly before and after the truck engine, it comprises an inner metal sleeve pipe, the outer coated one deck rubber of inner sleeve, form the cylinder of a band round platform, its lower end is inserted in the carriage, it is characterized in that the affixed dome in inner metal sleeve pipe upper end, inner sleeve is "T"-shaped, the outer coated rubber of dome below and inner sleeve, wear-resisting sheath of inner sleeve bottom rubber external fixation, pad of inner sleeve lower end grafting.
