Problems solved by technology

[0003] For example, patents CN201020539712.8 and CN201310574243.1 respectively disclose support structures for transmission shafts, but this support structure is mainly used for front and rear drive mini-cars, which cannot meet the needs of four-wheel drive SUV models for two-stage intermediate drive shafts. Higher requirements for mounting and fixing

Embodiment Construction

[0014] The present invention will be further described in detail below in conjunction with the accompanying drawings and examples. The following examples are only used to explain the present invention, and do not constitute a limitation to the protection scope of the present invention.

[0015] Such as Figure 1-Figure 5 The shown car transmission shaft installation and fixing structure includes a transmission shaft fixing crossbeam and a reinforcing crossbeam 3 which are welded and fixed on the front floor 4 and are located between the front crossbeam 5 installed on the front seats and the rear crossbeam 6 installed on the front seats. The transmission shaft fixing crossbeam and reinforcing crossbeam are symmetrically arranged on the lower surface and the upper surface of the front floor 4 respectively. The reinforcing crossbeam 3 is welded and fixed on the upper surface of the front floor, and the left and right ends of the reinforcing crossbeam are welded with the floor lef...

Abstract

The invention discloses an automotive transmission shaft installing and fixing structure which comprises a transmission shaft fixing cross beam fixed to the lower surface of a front floor. The transmission shaft fixing cross beam is composed of a cross beam body and a transmission shaft fixing seat welded and fixed to the outer surface of the cross beam body. A reinforcing cross beam symmetrical to the transmission shaft fixing cross beam in position is welded and fixed to the upper surface of the front floor. The automotive transmission shaft installing and fixing structure has better rigidity and intensity and can meet the requirements for bearing capacity and fixing reliability.

Description

technical field [0001] The invention relates to the field of automobile body structure, in particular to a novel installation and fixing structure of an automobile transmission shaft. Background technique [0002] At present, full-time four-wheel drive or timely four-wheel drive has become a must configuration for large SUVs. The intermediate drive shaft of four-wheel drive vehicles is divided into three-stage and two-stage types, and the two-stage intermediate drive shaft is more cost-effective than the three-stage type. , but the installation and fixation of the two-stage intermediate drive shaft is more difficult than the three-stage drive shaft. [0003] For example, patents CN201020539712.8 and CN201310574243.1 respectively disclose support structures for transmission shafts, but this support structure is mainly used for front and rear drive mini-cars, which cannot meet the needs of four-wheel drive SUV models for two-stage intermediate transmission shafts. Higher requ...
