Abstract
A kind of flywheel shell of engine, bell housing be connected with cylinder body and including：Inner casing, shell and the seal mounting hole positioned at center, the inner casing are connected with cylinder body, wherein：Have on the inner casing：Inner casing reinforcement, the inner casing reinforcement is originated to outer ring radiation in emitting shape and from the seal mounting hole, and it is connected upwardly to bell housing inwall, and ring stiffener, the ring stiffener in a ring and from the seal mounting hole originate to outer ring arrange, bell housing is aluminum alloy materials, but bell housing inwall is respectively arranged reinforcement, and low wall cloth puts annular and emission type cross reinforcing rib, improves flywheel shell intensity.
Description
Technical field
The utility model is on a kind of flywheel shell of engine.
Background technology
Bell housing is one of main parts size of engine, and main function is the shell as flywheel, connects transmission housing
Body and starter, as needed, the diameter of general bell housing is in more than 200mm, therefore the weight of bell housing is also very big.Bell housing
Structure is the big planar structure of thin-walled, and mode, the intensity of itself are all poor.
In the prior art in order to ensure the mode of bell housing and intensity, existing bell housing using casting iron type materials, causes more
Bell housing weight is very big, influences the overall weight of engine, and the energy-saving and emission-reduction to engine are also unfavorable.
Utility model content
The utility model provides a kind of flywheel shell of engine, bell housing be connected with cylinder body and including：Inner casing, shell and position
Seal mounting hole in center, the inner casing are connected with cylinder body, wherein：Have on the inner casing：Inner casing reinforcement, it is described interior
Shell reinforcement is originated to outer ring radiation in emitting shape and from the seal mounting hole, and is connected upwardly to bell housing inwall, and ring
Shape reinforcement, the ring stiffener in a ring and from the seal mounting hole originate to outer ring arrange.
Bell housing is aluminum alloy materials in the utility model, but bell housing inwall is respectively arranged reinforcement, and low wall
Arrangement annular and emission type cross reinforcing rib, improve flywheel shell intensity.
Brief description of the drawings
Fig. 1 is to scheme on the outside of the utility model；
Fig. 2 is to scheme on the inside of the utility model；With
Fig. 3 is the utility model assembling schematic diagram.
Reference：1 seal mounting hole, 3 inner casing reinforcements, 4 ring stiffeners, 5 shell reinforcements, the installation of 6 starters
Hole sealing surface, 7 gearbox mounting surfaces, 8 cylinder bodies, 9 bell housings, 10 fixed bolt holes.
Embodiment
As shown in Figures 1 to 3, the utility model provides a kind of flywheel shell of engine, and bell housing 9 is connected and wrapped with cylinder body 8
Include：Inner casing, shell and the seal mounting hole 1 positioned at center, wherein：Have on the inner casing：Inner casing reinforcement 3, the inner casing
Reinforcement 3 is originated to outer ring radiation in emitting shape and from the seal mounting hole 1, and is connected upwardly to bell housing inwall, and ring
Shape reinforcement 4, the ring stiffener 4 in a ring and from the seal mounting hole 1 originate to outer ring arrange.
Bell housing is aluminum alloy materials in the utility model, but bell housing inwall is respectively arranged reinforcement, and low wall
Arrangement annular and emission type cross reinforcing rib, improve flywheel shell intensity.
Bell housing is arranged on cylinder body, and its top half is connected with cylinder body and installs fixation, and internal stiffeners fly with these
Hub fixed bolt hole is connected, and improves flywheel shell intensity.
As a further improvement, the inner casing reinforcement 2 and the ring stiffener 4 have a plurality of respectively.
As a further improvement, a plurality of inner casing reinforcement 2 is included in the connection that is connected with fixed bolt hole 10
Shell reinforcement.
As a further improvement, have on the shell：Shell reinforcement 5, the shell reinforcement 5 in emitting shape simultaneously
Connect gearbox mounting surface 7.
As a further improvement, the shell reinforcement 5 have it is a plurality of, and a plurality of shell reinforcement 5 include with
The connected with outer casing reinforcement that fixed bolt hole 10 is connected.
As a further improvement, starter mounting hole sealing surface 6 is inclined plane.Compared with traditional right-angle surface, reduce
One face, the weight of bell housing 9 is alleviated, increase the arrangement space of engine.
As a further improvement, bell housing 9 top half width and thickness 90mm, the latter half thickness 50mm.Reserve
Plane installs sealing surface together with cylinder body bottom surface for oil sump, is easy to dismantle oil sump during maintenance.
The utility model provides a kind of bell housing of engine aluminum lightweight, bell housing preferred arrangement reinforcement, makes
Aluminum bell housing mode, intensity meet vehicular engine requirement, have the advantages of light weight.
It should be appreciated that the utility model scope of the claimed is not limited to non-limiting embodiments, it should be understood that non-limiting reality
Scheme is applied to illustrate as just example.The desired substantive protection domain of the application is more embodied in independent claims
The scope of offer, and its dependent claims.
