Description

Technical Field

[0001] This utility model relates to an installation structure for a low-temperature cold start device for heavy-duty trucks, belonging to the field of heavy-duty trucks. Background Technology

[0002] Currently, the existing low-temperature cold start device for heavy trucks is installed on the right front side of the main beam. Maintenance and repair of this device requires tilting the cab first, and personnel to crawl into the bottom of the cab. The operating space is small, and there is also a safety hazard that the cab may fall back and injure people due to the loss of pressure of the tilting cylinder. Utility Model Content

[0003] The purpose of this utility model is to improve the convenience of maintenance and repair, eliminate the safety hazard of the cab falling back and injuring people due to the depressurization of the tilt cylinder, and ensure compatibility with the existing chassis platform by not changing the original vehicle structure at the assembly fixing point position.

[0004] This utility model is achieved through the following technical solution:

[0005] A heavy-duty truck low-temperature cold start device installation structure includes a guide bracket 5 and a load-bearing bracket 2, which are made of bent sheet metal. The lower end of the guide bracket 5 and the horizontal plate of the load-bearing bracket 2 are detachably connected to and fixed to a heater assembly 3. The vertical plate of the load-bearing bracket 2 is detachably connected to the rear support assembly 1 of the cab. The horizontal plate at the upper end of the guide bracket 5 is tied and fixed to the tube bundle in the heater assembly 2 by a strap 4.

[0006] This invention improves the convenience of maintenance and repair, and eliminates the safety hazard of the tilting cylinder depressurizing and causing the cab to fall and injure people. Attached Figure Description

[0007] Figure 1 Main view of the installation structure of the low-temperature cold start device;

[0008] Figure 2 Exploded view of the installation structure of the low-temperature cold start device. Detailed Implementation

[0009] like Figure 1 , 2 As shown, this utility model is an installation structure for a low-temperature cold start device for heavy trucks. First, the vertical heater assembly 3 and the guide bracket 5 are pre-installed on the load-bearing bracket 2 by bolts. Second, the horizontal load-bearing bracket 2 is installed on the rear support assembly 1 of the cab by bolts. Finally, the straps 4 are used to bind and fix the tube bundle in the heater assembly 2. The installation structure is a sheet metal bending part, which has a simple processing technology and low production cost.

[0010] The key design feature of this utility model is that the components of the low-temperature cold start device can be pre-assembled, resulting in high integration, shortening the production line installation cycle, and facilitating maintenance. The assembly fixing point position does not change the original vehicle structure, achieving compatibility with existing chassis platforms.
