Embodiment 1

[0059] see Figure 1 to Figure 6 , an adjustable fender for a commercial vehicle, comprising a connecting rod 1, a fender 2 and an installation adjustment mechanism 3, one end of the connecting rod 1 is connected to a support seat 11, and the other end of the connecting rod 1 is connected to the installation adjustment mechanism The mechanisms 3 are connected, and the installation and adjustment mechanism 3 slides up and down along the fender 2; the fender 2 is fixedly connected with an installation card slot 21, and the installation card slot 21 includes a left card slot plate 22 that is left and right symmetrical and has the same structure , right draw-in groove plate 23, described left draw-in groove plate 22, right draw-in groove plate 23 all comprise vertical support plate 24, horizontal support plate 25, the bottom of vertical support plate 24 is vertically connected with fender 2, vertical support plate 24 The top of the top is vertically connected with the horizontal s...

Embodiment 2

[0062] Basic content is the same as embodiment 1, the difference is:

[0063] The clamping structure 5 includes a vibration-damping block 6 and a pressure plate 7. A vibration-damping perforation 61 is respectively provided at the upper and lower ends of the vibration-damping block 6, and a pressure perforation 71 is respectively provided at the upper and lower ends of the pressure plate 7. The upper and lower ends of the clamping plate 4 are respectively provided with a clamping bolt shaft 41, and the clamping bolt shaft 41 passes through the transverse branch gap 251, the vibration-damping perforation 61, and the pressure perforation 71 in sequence, and then is threadedly connected with the nut, and The damping block 6 and the pressing plate 7 clamp the other end of the connecting rod 1 together.

[0064] The connecting of the clamping plate 4 and the clamping structure 5 means that the clamping bolt shaft 41 passes through the transverse branch gap 251, the vibration-dampin...

Embodiment 3

[0066] Basic content is the same as embodiment 2, the difference is:

[0067] The damping block 6 includes an upper block 62, a concave body 63 and a lower block 64 from top to bottom, and the upper and lower ends of the concave body 63 are respectively connected with the upper block 62 and the lower block 64. , the middle part of the concave body 63 is provided with a sunken lower groove 82, and each of the upper block body 62 and the lower block body 64 is provided with a vibration-damping perforation 61; the pressure plate 7 includes an upper plate body from top to bottom 72, the convex body 73 and the lower plate body 74, the upper and lower ends of the convex body 73 are connected with the upper plate body 72 and the lower plate body 74 respectively, and the middle part of the convex body 73 is provided with a convex and connected with the lower plate body. The upper convex groove 81 corresponding to the groove 82, the upper convex groove 81 and the lower groove 82 surrou...

Abstract

The invention relates to an adjustable mudguard for a commercial vehicle. The adjustable mudguard comprises a connecting rod, a mudguard, a locking plate, a vibration attenuation block and a pressure plate. The locking plate slides up and down along an inner cavity of the mounting card slot fixedly formed along the mudguard; the top surface where the card slot is formed is in contact with the bottom surface of the vibration attenuation block; the locking plate, the vibration attenuation block and the pressure plate are successively connected as a whole; the vibration attenuation block and the pressure plate jointly clamp the other end of the connecting rod; during an application, the height of the mudguard is adjusted by means of relative slippage of the locking plate and the mounting card slot; and soft connection between the connecting rod and the mudguard is achieved as the locking plate, the vibration attenuation block and the pressure plate are relatively independent, so that the buffer effect is improved. The design not only is relatively strong in adjustability and relatively good vibration attenuation effect, but also is relatively low in mounting and adjusting difficulty and easy to operate.

Description

technical field [0001] The invention relates to a fender, which belongs to the field of automobile manufacturing, in particular to an adjustable fender for a commercial vehicle and a method for using the fender, which is particularly suitable for adjusting the height of the fender according to the size of the tire, and has better vibration reduction Effect. Background technique [0002] A traditional commercial vehicle fender bracket is mainly composed of a rod, a support, and a fender, wherein the support is fixed on the vehicle frame, one end of the rod is fixed on the support, and the other end is fixed on the fender. The fender of this structure cannot adjust the height of the fender according to the size of the tire, and cannot adapt to tires of different specifications. The rod and the fender are rigidly connected, which cannot absorb vibration, and are easy to damage the rod and the fender. [0003] The authorized announcement number is CN204821732U, and the utility...
