Abstract

The utility model relates to an automobile damping device, in particular to an improvement of the steel plate spring structure for heavy automobiles. The steel plate spring disclosed by the utility model comprises a first steel plate spring 4, a second steel plate spring 6, a third steel plate spring 7 which are fixed through a clip 3 and a bolt, and a plurality of plate springs which have a supporting effect and are fixed through a center bolt 2. Each of the two ends of the first spring 4 are provided with an independent spring eye tie-in 1; when the spring eye is broken, only the independent spring eye tie-in on the end of the first spring is needed to be dissembled and changed, which is convenient and quick. The steel amount needed by the independent spring eye tie-in 1 is much less than that needed by the whole first spring 4, and material cost is saved greatly when the independent spring eye tie-in 1 is maintained.

Description

A kind of leaf spring
Technical field
The utility model relates to a kind of vehicle shock-absorbing device, the particularly heavy-duty car improvement of leaf spring structure.
Technical background
The forward and backward leaf spring of present most of lorry generally all be two grasswort formulas, roughly constitutes to comprise: first an of fixation, and second and some passive leaf spring monolithics are fixed by centre bolt, and first two ends is grasswort.The major defect of this spring is that grasswort partly is stressed place, and the impact force of being born, vehicle-mounted gravity and other stress all concentrate on this.And in the vehicle driving process, along with vehicle pitching, be roughly fluctuating load, very easily cause the reduction of fatigue resistance, break at the grasswort place easily, working life is short.Lose because of grasswort is disconnected, whole leaf spring just is done for.As maintenance, need to change down disconnected first of having lost grasswort.What the Mechanical Help personnel will remove is not only first, also needs the centre bolt of dismantling, and takes off whole first, first of could more renew.No matter the time from repairing, the cost consideration of difficulty and first steel plate reed, its financial cost all are quite high.
Summary of the invention
The utility model has solved the grasswort place easy-rupturing that prior art exists, and leaf spring is changed the high problem of repair cost, and a kind of improved leaf spring structure is provided, and it can effectively address the above problem.
Above-mentioned technical purpose of the present utility model mainly solves by the following technical programs: the disclosed leaf spring of the utility model, comprise with first 4 of the leaf spring of clamp 3 and bolt, second 6, the 3rd 7, and some passive plate spring sheet, and fixing by centre bolt 2, described spring also is provided with individual volume terminal lug 1 on first 4 two.When grasswort place fracture, only need to remove individual volume terminal lug on first head like this, changed and get final product, convenient and swift.Independently individual volume terminal lug 1 usefulness steel will lack much compared with whole first 4, and the cost of material of saving during maintenance also is appreciable.
As preferably, first 4 on a kind of spring of leaf spring can be connected with some groups of bolts 5 with individual volume terminal lug 1.The easy accessibility that is threaded can be saved the time of maintain and replace individual volume terminal lug 1, allows the driver set out on a journey again as early as possible, continues future.
As preferably, first 4 two of a kind of spring of leaf spring is half grasswort, and half grasswort is protecting the little grasswort of individual volume terminal lug 1.First half grasswort plays a part to support and protect little grasswort, strengthens anti-fatigue ability herein.
As preferably, first 4 two of a kind of spring of leaf spring can be straight sheet.Though straight sheet descends on fatigue resistance to some extent, maintenance and installation is more convenient.
As preferably, the connecting bolt 5 that first 4 on a kind of spring of leaf spring and individual volume terminal lug are 1 is no less than two groups.Because vehicle towed power is very big, no matter single group bolt on connection stability and reliability, all is far from being enough, should rationally increase the group number of bolt according to the vehicle tonnage, and be reasonable Arrangement, can prevent that just bolt from being cut off by powerful shearing stress.
As preferably, have some waist shaped holes 8 in a kind of individual volume terminal lug 1 of leaf spring.Waist shaped hole 8 layouts like this can make things convenient for attachment hole on first docks, to adapt to the leaf spring that differs with various width.
Advantages such as therefore, the utility model is simple in structure, and the individual volume terminal lug that is provided with on first has the raw material of saving and expense, and is easy to maintenance.

Specific embodiment
Below by embodiment, and in conjunction with the accompanying drawings, the technical solution of the utility model is described in further detail.
Embodiment 1: with reference to Fig. 1,2,3, the disclosed leaf spring of the utility model comprises with first 4, the second 6 of the leaf springs of clamp 3 and bolt, the 3rd 7, and some passive plate spring sheet, and fixing by centre bolt 2, also be provided with individual volume terminal lug 1 on first 4 two.First 4 with individual volume terminal lug 1 between be connected with four groups of bolts.First double headed roller half grasswort, half grasswort is protecting the little grasswort of individual volume terminal lug 1.
Embodiment 2: with reference to Fig. 4,5,6, embodiment and difference implement 1 only first 4 and and the attachment portion of individual volume terminal lug 1, but its working principle and the former are identical.Two of first 4 of present embodiment is a straight peen, has three waist shaped holes 8 in the individual volume terminal lug 1.
