The content of the invention
Problems to be solved by the invention
But in the brake of above-mentioned patent document 1, when liner plate to be installed to the end of axletree, lead in axletree
The parts such as bearing are configured with around hole, therefore, are restricted by installing space, it is necessary to set pressure plates according to installing space
Shape, wall thickness.In addition, in the brake of above-mentioned patent document 2, reinforcement structure is installed in the whole peripheral part of liner plate
Part, therefore, weight increase.
Then, it can not restricted by installing space it is an object of the present invention to provide a kind of and not make weight as far as possible
Strengthen the vehicle drum brake of liner plate on the premise of increase.
The solution used to solve the problem
In order to achieve the above object, vehicle drum brake of the invention will slide in the inside of liner plate with brake drum connects
Tactile brake-shoe storage for it is scalable freely, and with the brake-shoe hold-down mechanism to be exerted a force to side where liner plate to the brake-shoe,
Characterized in that, the position in addition to the outer peripheral edge of the liner plate to vehicle body when installing as the part on top is provided with
Flange shape reinforcing plate.
It is further preferred, that the reinforcing plate is located at the outer of that side opposite with side where vehicle body from the liner plate
Surface protrudes laterally.Additionally it is preferred that the reinforcing plate be arranged on when to vehicle body install liner plate when the liner plate at least
Than the position of the brake-shoe hold-down mechanism on the lower.
The effect of invention
Using the vehicle drum brake of the present invention, reinforcing plate is provided with by the outer peripheral edge in liner plate, can not be by
Strengthen liner plate to the restriction of installing space, moreover, strengthen the outer circumferential side of liner plate by using flange shape reinforcing plate, can be with simple
Construction strengthen liner plate with not increasing weight as far as possible.In addition, in the state of liner plate is installed on vehicle body liner plate outer peripheral edge
The position as top be not provided with reinforcing plate, leaked into therefore, it is possible to suppress rainwater from outside along reinforcing plate in liner plate
Portion.
Moreover, by making the outwardly pleurapophysis that is located at vehicle body where side opposite that side of the reinforcing plate from liner plate
Go out, the liner plate of existing drum brake can not carried out simply strengthening liner plate on the premise of significantly shape changes.
In addition, to vehicle body install liner plate when liner plate the position at least than brake-shoe hold-down mechanism on the lower be provided with plus
Strong plate, the inside of liner plate is leaked into along reinforcing plate so as to suppress rainwater in the rainy day from outside.

Embodiment
Fig. 1 to Fig. 6 be represent the present invention vehicle drum brake a form example figure, the vehicle drum brake
Device 1 has a pair of the brake-shoes 3,3 for being formed as arch in the internal surface configurations for the liner plate 2 for being fixedly installed on vehicle body, makes two brakings
One end of hoof 3,3 abuts with the piston 4a of wheel brake cylinder 4, and the other end abuts with anchoring piece 5.
The vehicle is brake-shoe 3,3 is expanded to the radial outside of liner plate 2, so that the lining of periphery with drum brake 1
Piece 3a, 3a are slided on brake drum (not shown) to realize the leading and driven shoe brake of braking action, utilize support shaft
The provided at one of parking brake lever 6 is supported on a brake-shoe 3, and by the system for drawing parking brake lever 6
Running wire 7 is linked to the other end of the parking brake lever 6.
Each brake-shoe 3 includes such as lower part：Disc 3b, edge and disc 3b outer rim with the configured in parallel of liner plate 2 intersect
Direction be fixedly installed on disc 3b wheel rim 3c and the above-mentioned liner 3a being pasted onto on wheel rim 3c outer peripheral face.Each system
Dynamic hoof 3 compresses pin 8 and brake-shoe holddown spring 9 by the other elastic bearing of disc 3b substantial mid-portion in liner plate using brake-shoe
2, the brake-shoe to be exerted a force to side where liner plate to brake-shoe 3 is formed using brake-shoe compression pin 8 and brake-shoe holddown spring 9 and is compressed
Mechanism 10.In addition, between two disc 3b, brake-shoe return spring 11 is provided with the inner side of wheel brake cylinder 4, is being anchored
The outside of part 5, which is provided with, links spring 12, two brake-shoes 3 is exerted a force along undergauge direction all the time, moreover, brake clearance is adjusted automatically
Engagement positions 13 are configured by the inner circumferential side of the spring 11a in brake-shoe return spring 11 in a manner of.
In center formed with axletree through hole 2a, the upper side when the axletree through hole 2a installs to vehicle body offers liner plate 2
The positioning hole 2b of wheel brake cylinder.Axletree through hole 2a lower side so that the sheet material internally side parallel ridges of liner plate 2
Mode offers rivet hole 2d, 2d formed with anchor mounting part 2c in anchor mounting part 2c.In addition, in axletree through hole
2a left and right sides portion, respectively it is being arranged with 3 convex face 2e respectively with arc-shaped with 3 corresponding position of brake-shoe, is making liner plate 2
Sheet material internally side parallel ridges and form convex face 2e.
In addition, flange shape reinforcing plate 14 is installed in the outer peripheral edge of liner plate 2.Reinforcing plate 14 to vehicle body from installing when ratio
Brake-shoe hold-down mechanism 10,10 is set slightly by outer peripheral edge of the lower section along liner plate 2 that be positioned against of top, and reinforcing plate 14 includes installation
The outer peripheral edge of portion 14a and protuberance 14b, above-mentioned installation portion 14a along liner plate 2 is arranged on being located at and side phase where vehicle body for liner plate 2
On the outer surface 2f of that anti-side, above-mentioned protuberance 14b is from installation portion 14a outer peripheral edge to opposite with side where vehicle body
That side and installation portion 14a outer peripheral edge are substantially at right anglesly prominent.
As described above, this form example in the state of liner plate 2 is installed on vehicle body from than brake-shoe hold-down mechanism 10,10
Slightly by top be positioned against lower section flange shape reinforcing plate 14 is installed on the outer peripheral edge of liner plate 2, therefore, it is possible to not by
Strengthen liner plate 2 on the premise of the part around axletree through hole 2a is configured to the restriction of installing space.Moreover, by liner plate 2
The position as top of the outer peripheral edge of liner plate 2 is not provided with reinforcing plate 14 in the state of being installed on vehicle body, therefore, it is possible to suppress
Rainwater leaks into the inside of liner plate 2 from outside along reinforcing plate 14.In addition, utilize convex with installation portion 14a and protuberance 14b
The reinforcing plate 14 of edge shape strengthens the outer circumferential side of liner plate 2, so as to strengthen liner plate 2 well with simple construct, and can
Prevent weight from increasing as far as possible.Moreover, can be before significantly shape change not be carried out to the liner plate 2 of original drum brake
Put simply reinforcement liner plate 2.
In addition, it is not limited to the leading drum brake with driven shoe type, energy described in present invention form example described above
Enough apply in any kind of drum brake.In addition, the installation site of reinforcing plate is not limited to above-mentioned form example, only
Be arranged on the outer peripheral edge of liner plate when being installed to vehicle body as the part on top in addition to appropriate position.
