Technical field
The utility model relates to a kind of driving mechanism, the inner drive sleeve assembly that connects air compressor and hydraulic steering pump of particularly a kind of vehicular engine.
Background technique
Air compressor of the prior art generally is that the air compressor rear end is connected hydraulic steering pump with the hydraulic steering pump Placement, because the motor complete machine is arranged, end spaces is taken by other part behind the air compressor, on the basis of end spaces, hydraulic steering pump can't be installed after not increasing air compressor.
Summary of the invention
For overcoming the shortcoming that exists in the above prior art, the utility model provides a kind of drive sleeve assembly, hydraulic steering pump can be installed in the front end of air compressor, export to hydraulic steering pump by the moment that this drive sleeve assembly will act on the air compressor crank, thereby drive the fluid-link steering pump work.
Drive sleeve assembly of the present utility model is installed on the air compressor crankshaft front end, comprises driving mechanism, and driving mechanism one end is connected with bent axle, and the other end is connected with the fluid-link steering pump shaft.
In technique scheme, driving mechanism can comprise external gear, crankshaft hole and splined hole, and external gear transmits outside moment, and driving mechanism is set on the bent axle by crankshaft hole, and is set in by splined hole on the splined shaft of hydraulic steering pump.
In technique scheme, have a containing space between crankshaft hole and the splined hole, the flange surface nut of fixed crankshaft and driving mechanism is positioned at described containing space.
In technique scheme, the bent axle end can be thread spindle, and flange surface nut and thread spindle are suitable; The splined shaft of splined hole and hydraulic steering pump is meshing with each other.
Drive sleeve assembly of the present utility model is installed on the air compressor crankshaft front end, can realize the transmission requirement that hydraulic steering pump and air compressor rotate simultaneously and work, compact structure, and it is little to take up room, safe and reliable, with low cost.

Fig. 3 is that the A-A of Fig. 2 is to sectional view.
Mark the following drawings mark thereon in conjunction with the accompanying drawings:
The 1-air compressor; 2-drive sleeve assembly; The 3-flange surface nut; The 4-gear chamber; The 5-hydraulic steering pump; The 6-external gear; The 7-splined hole; The 8-crankshaft hole; The 9-bent axle; The 10-splined shaft; The 11-containing space.
Embodiment
Below in conjunction with accompanying drawing, an embodiment of the present utility model is described in detail, but is to be understood that protection domain of the present utility model is not subjected to the restriction of embodiment.
As shown in Figure 1 to Figure 3, drive sleeve assembly 2 of the present utility model is installed on bent axle 9 front ends of air compressor 1, comprises driving mechanism, and driving mechanism one end is connected with bent axle 9, and the other end is connected with the axle of hydraulic steering pump 5.Driving mechanism comprises external gear 6, crankshaft hole 8 and splined hole 7, and the moment that external gear 6 transmits from the outside passes to hydraulic steering pump 5 by above-mentioned driving mechanism.Driving mechanism is sleeved on the bent axle by crankshaft hole 8, and is set in by splined hole 7 on the splined shaft 10 of hydraulic steering pump.Have a containing space 11 between crankshaft hole 8 and the splined hole 7, the flange surface nut 3 of fixed crankshaft 9 and driving mechanism is positioned at described containing space 11.The bent axle end can be thread spindle, and flange surface nut 3 is suitable with thread spindle.Splined hole 7 is meshing with each other with the splined shaft 10 of hydraulic steering pump.
Installation process as shown in Figure 1, drive sleeve assembly 2 is installed in the crankshaft front end of air compressor 1, flange surface nut 3 is put into from the splined hole of drive sleeve assembly 2, on be tightened on the bent axle thread spindle of air compressor 1, flange surface nut 3 will be tightened on the bent axle of air compressor 1 on the drive sleeve assembly 2.The air compressor 1 that installs drive sleeve assembly 2 is installed on the gear chamber 4 by the air compressor positioning spigot (not shown) of gear chamber 4.Hydraulic steering pump 5 is installed from the steering pump positioning spigot (not shown) of gear chamber 4 the other ends, the splined hole engagement of the splined shaft of hydraulic steering pump 5 and drive sleeve assembly 2, and hydraulic steering pump can be installed on the gear chamber 4.The coaxality of air compressor positioning spigot and hydraulic steering pump positioning spigot need guarantee on the gear chamber 4.
As Fig. 2, shown in Figure 3, be processed with external gear 6 and splined hole 7 on the drive sleeve assembly 2, external gear 6 is equivalent to the air compressor gear, by gear engagement, drives the air compression machine crankshaft and rotates, thereby realize air compressor 1 work.Leave enough containing spaces between external gear 6 and the splined hole 7 and can put down flange surface nut 3 and tighten wrench, avoid the crankshaft front end of air compressor 1 and the splined shaft front end of hydraulic steering pump 5 to collide simultaneously.The splined hole 7 of drive sleeve assembly 2 meshes with the splined shaft of hydraulic steering pump 5, and the axle that drives hydraulic steering pump 5 rotates.Thereby realize hydraulic steering pump 5 work.
Drive sleeve assembly of the present utility model is installed on the air compressor crankshaft front end, and it is little to take up room, compact structure, and can satisfy air compressor and the same rotary speed working of hydraulic steering pump.
More than disclosed only be a specific embodiment of the present utility model, still, the utility model is not limited thereto, any those skilled in the art can think variation all should fall into protection domain of the present utility model.
