Embodiment Construction

[0015] A combination structure of leaf spring clamps for heavy-duty dump trucks, including a U-shaped leaf spring clamp 1, side holes 2 are opened on both sides of the leaf spring clamp 1 near the U-shaped opening, and bottom holes 3 are opened at the bottom ; It also includes a clamp seat 4 that is movably connected between the U-shaped openings of the leaf spring clamp 1; The structure has a rivet hole 5 riveted with the lowermost piece of the leaf spring and the leaf spring clamp 1; the leaf spring clamp 1 is made of a steel plate with a thickness of 8 mm and a width of 30 mm.

[0016] The clamp seat 4 includes a pair of longitudinal plates 6, a pair of transverse plates 7 are connected between the ends of the two longitudinal plates 6, and both ends of each longitudinal plate 6 extend outward with a limiting plate 8 and the limiting plate 8 The plate 8 and the horizontal plate 7 together form a position-limiting structure; the middle part of the vertical plate 6 is connect...

Abstract

The invention relates to a part for an automotive suspension, in particular to a plate spring clamp combined structure for a heavy-load dumper. The plate spring clamp combined structure for the heavy-load dumper comprises a clamp base which is connected between a plate spring and a U-shaped opening of a clamp; the clamp base is matched with the plate spring clamp for use; holes are formed in two sides, close to the U-shaped opening, of the plate spring clamp and are used for assembling connecting bolts; rivet holes are formed in the bottom the plate spring clamp and are used for riveting the bottommost piece of steel plate springs with the clamp base and the clamp through rivets; each of two ends of the clamp base is of a limiting structure which is used for limiting the plate spring clamp; riveting holes which are riveted with the steel plate spring pieces and the bottom edge of the clamp are formed in the middle structure of the clamp base; the plate spring clamp is made of a steel plate which is 8mm thick and 30mm wide in specification. The plate spring clamp combined structure is convenient to produce and convenient in assembly technology and meets the condition of batch production; the transitional design of the clamp base is added, so that the stress at the bending part of the clamp steel plate is eliminated; the design concept of the plate spring clamp continues to be used; the design life of the plate spring clamp is ensured.

Description

technical field [0001] The invention relates to parts for automobile suspension, in particular to a combination structure of leaf spring clips for heavy-duty dump trucks. Background technique [0002] The leaf spring is one of the important components of the automobile suspension. It elastically connects the frame and the axle. Its function is to transmit the force and moment acting between the wheel and the frame, and to buffer the vehicle from the uneven road surface. The impact load of the frame or body, and attenuate the vibration of the bearing system caused by it, so as to ensure that the car can run smoothly. The effect of the leaf spring clamp is to ensure that the leaf spring sheet bears the sprung mass or the impact from the ground at the same time. [0003] With heavy-duty dump trucks being put into use in large quantities in open-pit mines, the leaf springs of the vehicles are bearing more and more loads, especially in bumpy mine road conditions, due to the insu...
